Security Reporting

This page provides our public process for reporting security vulnerabilities, privacy concerns, and suspected incidents.

Last updated: August 20, 2026

1. What to report

Report suspected security vulnerabilities, privacy concerns, unauthorized access, or actual or suspected misuse of VastSell or Amazon data.

2. How to report

Email admin@vastsell.com with the subject “Security report”. Include a clear description, affected URL or feature, reproduction steps, and business impact. Do not include passwords, access tokens, buyer information, or other sensitive data in the initial email.

3. Acknowledgement and tracking

We aim to acknowledge reports within two business days. We assign an internal case reference, assess severity, preserve relevant evidence, and provide status updates through the verified reporting channel.

4. Response and resolution

We investigate, contain, remediate, and validate reported issues according to risk. Where required, we notify affected customers, Amazon, regulators, or other authorities in accordance with applicable obligations.

5. Responsible disclosure

Please make a good-faith effort to avoid privacy violations, service disruption, destructive testing, or accessing data beyond what is necessary to demonstrate the issue. Allow reasonable time for remediation before public disclosure.
